Causes of snoring:

As mentioned in a previous post Medical studies show that sleeping in a prone position, or on your back, increases obstructions to breathing which makes you snore.
In deep sleep, the muscles in the roof of your mouth, tongue and throat relax. The tissues in your throat can relax enough that they vibrate and may partially obstruct your airway. The more narrowed your airway, the more tissue vibration increases, which makes your snoring grow louder.
Having a low, thick soft palate or enlarged tonsils or tissues in the back of your throat (adenoids) can narrow your airway. In addition, if the triangular piece of tissue hanging from your soft palate (uvula) is elongated, airflow can be obstructed and vibration increased.
Being overweight can cause extra weight can build up in your throat and contribute to narrowing of your airway.
Consuming alcohol before bedtime relaxes throat muscles and decreases your natural defenses against airway obstruction.
Chronic nasal congestion or a crooked partition between your nostrils (deviated nasal septum) may contribute to snoring.
Sleep Apnea. Obstructive sleep apnea is the most common type of sleep apnea. It occurs when the soft tissue in the back of the throat relaxes during sleep, causing a blockage of the airway (as well as loud snoring). With obstructive sleep apnea, periods when breathing slows or stops occur at least five times an hour.
